The Paket-E/NK small-sized anti-submarine system with anti-torpedo is designed:

The complete set of the Paket-E/NK comprises:

- Paket-E control system

- rotating or fixed launching units

- Paket-AE specialized target designation sonar

- combat modules mounted on the launchin unit

Depending on missions assigned to the surface ship, its launching units can house combat modules armed with different combinations of small-sized heat-seeking torpedoes and/or anti-torpedoes, both in nomenclature and in quantity.

The small-sized heat-seeking torpedo is designed to engage enemy submarines, and the anti-torpedo is designed to intercept and destroy attacking torpedoes. Both are housed in unified transport-launch containers.

The Paket-E/NK system can operate independently or be integrated into ship's antisubmarine/anti-torpedo defence system, solving a number of tasks in fully automatic or automated modes, such as:

- generation of target designation data for small-sized heat-seeking torpedoes, based on data, provided by ship's sonar systems and posts

- detection and classification of attacking torpedoes, determination of their movement parameters, and generation of target designation data for anti-torpedoes
